Make the Pepper proxy support in-process font rendering.

This implements a WebKit thread in the PPAPI plugin process so we can do the
font calls without IPC. The existing font support was refactored into
a virtual class (to prevent PPAPI from depending on WebKit and creating a
circular GYP dependency).

This moves the renderer sandbox support into content/common so that it can
be used by the PPAPI process.
